How Does a Vasectomy Reversal Work?

Updated on October 8, 2018

Q: What is a vasectomy reversal and how does it work?

A: A vasectomy reversal is a surgical procedure that opens up these tubes and restores the flow of sperm through the vas deferens. The vasectomy reversal is usually performed by an experienced surgeon, usually a urologist, using specialized instruments, including an operating microscope. There are two types of vasectomy reversals: vasovasostomy and vasoepididymostomy.

A vasovasostomy is the operation most frequently performed for vasectomy reversal. It entails stitching the cut ends of the vas deferens together. If there is excessive inflammation or scarring in the epididymis, sperm may be blocked from getting to the vas deferens, so merely connecting the two cut ends of the vas deferens (as is done in a vasovasostomy) will not solve the problem. To bypass the blockage in the epididymis, a vasoepididymostomy must be performed.

A vasoepididymostomy is performed by connecting the vas deferens directly to the epididymis. One end of the vas deferens is stitched directly to the epididymis.
